Muster Roll for the ship, the Nassau , 1792.
The ship, the Nassau left Bristol for the Isle de los, off Sierra Leone. 190 enslaved Africans were taken across the Atlantic. The cook John Robertson, and Thomas Jones, a 1/2 seaman, were Africans. Both came back with the ship to Bristol.

The muster roll is a list of all crew signed on for all or part of a voyage, which was used to calculate the money each man should pay to the Sailors Hospital Fund (insurance).

The Society of Merchant Venturers is a Bristol-based organisation, which was formed in 1552 as an elite body of merchants involved in overseas trade. The Society still exists today.
